ABSTRACT
Optimizing the displacements that occur in a city, thereby reducing CO2 emissions and urban traffic congestion, makes large road tunnels an infrastructure that is increasingly in demand in cities that aspire to be “Smart cities”. These infrastructures are very often the star projects of the cities that undertake these projects, and their expectations in terms of performance, sustainability and social and environmental impact are rising every time. It is also a type of project in which significant technical advances have been made in the last 10 years in terms of design, construction methods and control systems.
The Legacy Way Project in Brisbane is a good example of this. The tunnel was recently opened to the public, in May 2015.
